Get expert help from the RHS to deal with pests and other problems
Keep a watchful eye for signs of vine weevil beetles nibbling the edges of leaves and their grubs who will be munching on roots below the surface.
Red berry mite is a microscopic invertebrate that is a common cause of uneven ripening of blackberries.
Rhododendron leafhopper causes little direct damage, but can be a problem as it is thought to spread a fungal disease known as bud blast that kills flower buds.
Often affecting wild roses or species roses, robin's pin cushion is a harmless, abnormal growth on the stems of roses consisting of a hard woody structure with an outer covering of moss-like leaves, which are either reddish pink or yellowish green in colour.
Roses can be spoiled by heavy infestations of sap sucking aphids (greenfly, blackfly and related insects) during spring and summer.
These small sap-sucking pests cause mottling on the leaves of roses and some other rosaceous trees and shrubs.
Rose leafhopper can cause a course pale mottling to the leaves of roses and some other related plants.
Rose leaf-rolling sawfly causes tightly rolled leaves on wild and cultivated roses. This damage is sometimes mistaken for weedkiller damage.
Roses seem to suffer from more than their fair share of problems. It is probably partly because this much-loved plant is so widely grown, often in formal rose borders or gardens, and any pest, disease or other problem is soon noticed. That said, some of the older varieties in particular can be very prone to foliar diseases.
The presence of large numbers of rose root aphid eggs on rose stems can cause concern, however the activities of the root feeding insects rarely damage plants.
The grazing activities of the slug-like larvae of the rose slugworm sawfly can cause leaves on roses to turn brown and dry up.
